Eagle Lake vs Stalker Lake
Water quality, depth, fish species, and recreation comparison.
Eagle Lake has a higher water quality grade (A, Excellent) than Stalker Lake (C, Fair). Both are in Otter Tail County, Minnesota.
Both Eagle Lake and Stalker Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. The grades are meaningfully apart: Eagle Lake grades a A while Stalker Lake grades a C. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.
For a recreational visitor, the wider grade gap is decisive — Eagle Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?

Side-by-Side Metrics
| Metric | Eagle Lake | Stalker Lake |
|---|---|---|
| Overall Grade | A (Excellent) | C (Fair) |
| Water Clarity | 22.6 ft | 6.6 ft |
| Phosphorus | 5 µg/L | 22 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 46 ft | 95 ft |
| Surface Area | 907.4 acres | 1.4K acres |
| Public Access | Yes | Yes |
| Fish Species | 10 | 17 |
| Trophic State | oligotrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Eagle Lake wins on overall water quality with a Grade A versus Stalker Lake's Grade C. Water clarity: 22.6 ft vs 6.6 ft. For more fish-species variety, Stalker Lake edges ahead with 17 documented species.
